Can not change keyboard layout in fresh Qubes 4.1

I want to have german layout in the whole system if I connect the keyboard. I mean, I set in on installation process.

In the system settings of dom0 is german layout but not in the VMs. I make settings always in TemplateVMs ofcource. localectl status in dom0 shows german. But in the templateVM VC Keymap: n/a and X11 Layout: n/a. Even after reboot.

As it seems, its similar problem as here: Keyboard layout issue - #13 by qun
